UV-K5 Troubleshooting
From "PC can't see it" to "I bricked it" — the high-frequency fixes.
PC can't see the device
Confirm flash mode (PTT+power, screen off/light on); use native Chrome/Edge (Snap has no access); install the CH340 driver on Windows; on Linux add your user to the dialout group.
No Update / Flash button
You’re not in the bootloader. Redo: power off → hold PTT and power on → light on, then connect the cable.
Flashed something bad
Don’t panic: the bootloader is always kept. Reflash a good firmware with the factory tool or egzumer WebUSB — almost never bricks.
Inaccurate battery %
Custom firmware offers a hidden battery calibration menu (power on while holding FN1+PTT, then Menu 67 BatCal). Follow prompts to recalibrate.
Legal reminder
⚠
Extended receive “listen only” is legal; transmitting outside amateur bands must be compliant and licensed. Monitoring police/emergency may be illegal.
Power loss mid-flash?
The bootloader survives; just reflash — usually no harm to recovery.
CHIRP can't read the K5?
Pick Quansheng UV-K5(8); egzumer needs the dedicated driver module loaded.
Can USB-C flash directly?
The K5’s USB-C actually routes through the mic/speaker serial; use the programming cable or K-plug adapter to enter.
